IMPROVEMENT IN FRICTlON-CLUTCH COUNTER-SHAFTS.

Specification forming part of Letters Patent No. 152,043, dated June 16,1874; application filed October 4, 1873.

To all whom yit may concern.:

Be it known that I, ELI J. MANVILLE, of

the city of IVaterbury and county of New Haven, and in the State ofConnecticut, have invented a new and useful Improvement inFriction-Clutch Counter-Shafts; and the following is declared to beafull, clear, and correct description of the said invention.

`springs to that extent that they become inoperative.

The object of my improvement -herein described is to obviate all ofthese difficulties, and, consequently, to render them more serviceableand easier to operate by producing a prompt and positive action in thereversing parts of the machine'.

Figure 1 is a-n end view of the machine. Fig. 2 is a longitudinalsectional view with the shaft through the line .fr af, and Fig. 3 is aYdetail of the lever-arm.

A is the frame of the machine, upon which all of the working parts arerun and supported. B is the shaft, which may carry any kind of a pulleythat maybe required. Fitting loosely on the shaft B is a sliding disk,C, which has a longitudinal movement on the said shaft, and sliding overa key, f, iirmly embedded in the shaft B. Surrounding the sliding disk Cand running loose upon the shaft B are two loose pulleys,-D D, alsorunning in opposite directions to each other by two driving-belts- Thissliding disk C has two' beveled faces turned upon its periphery, andexact-ly correspending in shape to the inner surfaces of the n driving-pulleys D and D.

Motion is communicated to the sliding disk C by means of the Vrod a,which passes through the hollow end of the shaft B, and is attached tothe said disk by means of the pin d passing through the hub of said diskand through the shaft B, and also through the end of the rod c. Theshaft at the point where the pin d goes through has a slot made in it,so that the movable disk may slide freely along the shaft.

At one Aend of the frame A is a boX or sleeve bearing, E, in which thehollow end of the shaft Bruns. the frame A, so that it will move in itsplace around, so as to give any desired slant or incline to theshipping-lever that is attached to the lever-arm II, and is secured inplace by any competent means. At the extreme end of the box E is ahollow slide, h, that moves freely in the said box, and through the saidslide It the rod a runs freely, having a shoulder at one end ot' theslide h, and on the opposite end of said slide it is provided with anut, m. Firmly secured to the slide h is a stud, 7J, which projectsthrough an elongated opening' in box E. This said box is made smooth andiiat on one side, and in the cen ter of its circle is a stud, S, onwhich the levcr-arm H swings. An elongated and angular opening, b, ismade in the horizontal end of the lever-arm H, that corresponds in widthto the diameter of the stud L in the hollow I slide h,lso that as thelever-arm is made to swing 011 its center at S it will cause the hollowslide h to traverse in either direction, as may be desired, thuscompelling the disk C, through the rod c, to move in a positive manner.

Placed between the two flat surfaces of the box E and the lever-arm H issecured a thin piece of leather, paper, or other similar sul stance, 0,in order to produce a sufficient amount of friction between the two datsurfaces of E and H, so that by screwing up the set-screw r/ thelever-arm H can always be made to stay at any place or position that itmay be placed, and at the same time prevent the possibility ofthe working back of the disk C from the pulleys D and D.

The vertical portion of the lever-arm H has a recess made in it toreceive a wooden handle that is bolted to it, and can be made to extenddown within reach of the operator.

Thus it will be clearly seen that by the This said box is fitted into 2.The combination of the box With the amy guiar slotted lever H,substantially as Shown and described.

3. In combination with the connecting-rod a, the tubular slide h andstud 7c, operating together substantially :is set forth.
